In this study, 'Naian Dalishi' as the main raw material, developed a special security features additives of seed coating agents in corn and wheat, by measuring physiological and biochemical and biological characteristics, obtain special functional additives for the prevention and control effect on seed coating side effects, and to some extent improve the resistance in disease of corn and wheat, in the early corn and wheat seed germination and seedling. The special security features additive was named NA-MY. The results are as follows:1.The laboratory test results showed that thiram tebuconazole FSC on corn reduced germination emerge 16.5% and vigor index 0.1, however, by mixing NA-MY and the seed coating agents, which could enhance the germination emerge 32.5%, vigor index 1.2 as compared with the uncoated seed; The mixtures consisting of NA-MY and �Shuang Ban Wang� seed coating agents(the main ingredient: imidacloprid and difenoconazole) also equally enhance the germination emerge 50% and vigor index 18.6 as compared with the uncoated wheat seed; By measuring physiological and biochemical during seed germination, the corn seed coating agents(thiram tebuconazole) and the wheat seed coating agents (�Shuang Ban Wang�)were found to slow the degradation of soluble starch and reduce the total soluble sugar content, thereby inhibiting the germination of the corn and wheat, but through NA-MY can accelerate the degradation of starch, promote the generation of total soluble sugars, thereby promoting seed germination, Which may be the cause that high germination potential of the corn and wheat seeds treatment with the mixtures consisting of NA-MY and seed coating agents.2.The field test results showed that the �Shuang Ban Wang� seed coating agents on wheat reduced fresh weight 0.2g, POD 1.75U, root vigor 21.6mg/g, chlorophyll 0.28mg/g, however, by mixing NA-MY and the seed coating agents, which could enhance the fresh weight 1.1g, POD 1.2U, root vigor 14.4mg/g, chlorophyll 0.33mg/g as compared with the uncoated seed; The mixtures consisting of NA-MYand thiram tebuconazole FSC also equally enhance the fresh weight 0.59g, POD 7.6U, root vigor 23.2mg/g, chlorophyll 0.28mg/g as compared with the uncoated corn seed.
